Playing back with high
quality sound codec
(AAC/LDAC)
This system can receive data in the
AAC or LDAC codec format from a
BLUETOOTH device. It provides a
playback with higher sound quality.
You can select an audio codec option
from the following two settings by
using “SongPal” (page19). The
default setting of this system is
“AAC ON.”
To apply the changes of the setting,
you need to terminate the BLUETOOTH
connection (page17), and then
perform the BLUETOOTH connection
again.
• AAC ON: The system detects the
codec used on the source device
and automatically selects the
optimal codec from “SBC,” “AAC*” or
“LDAC*.”
• AAC OFF: “SBC” is always applied
regardless of the codec used on the
source device.
* Available only when the codec is
supported by your BLUETOOTH device.
Note
You can enjoy higher sound quality when
the source device is compatible with
AAC/LDAC and this function is set to
“AAC ON.” However, the sound may be
interrupted depending on the conditions
of the BLUETOOTH communication. If this
happens, set the function to “AAC OFF.”
LDAC is an audio coding
technology developed by Sony,
that enables the transmission
of High-Resolution (Hi-Res)
Audio content, even over a
BLUETOOTH connection. Unlike
other BLUETOOTH compatible
coding technologies, such as
SBC, it operates without any
down-conversion of the Hi-Res
Audio content
1)
. It also allows
approximately three times more
data
2)
than the other technologies,
for transmitting over a
BLUETOOTH wireless network with
unprecedented sound quality using
efficient coding and optimized data
bundling.
1)
Excluding DSD format contents.
2)
In comparison with SBC (Sub Band
Codec), when the bit rate of 990 kbps
(96/48 kHz) or 909 kbps (88.2/44.1 kHz)
is selected.
